Graphics Adapter

I have tried a number of graphics adapters to increase to 256bit colours from 16 colours.

I got the laptop blank on ebay and i am put on as much stuff as i can

OS Win98

CPU Mobile Intel P3 IIIE,500MHZ
Motherboard Name Dell latitude Corporation Latitude Csx H500XT
Motherboard Chipset Intel 82440bx/zx
Present adapter =standard pci adapter (VGA)

I have tried the following adapters to no avail

Riva128-3[1]37W9xAGP (as advised perviously to another member)

Nmgc5
Any suggestions

 

What i need is an appropriate driver for the chipset i have.As previously mentioned i have tried a number of them but to no avail, the computer. The responce i get is "the driver you have chosen was not written specifically for the selected hardware and may not work correctly.Installing this driver is not recommended"

Maybe i am installing it wrongly but i dont know i think i am but any of the new drivers i try are not recognised

 

Issue resolved. I installed a driver from neomagic and its works perfectly now.
Thanks anyway
